View 1 RepliesPontiac - Montana :: Loud Clunking Noises From 2005 Minivan SV6
I have a Pontiac Montana minivan SV6 that is making strange clunking noises from possibly the rear or middle of the van when I go over a bump, large or small. I have had it in to our local mechanic and the local tire/repair shop and transmission shop. They have not been able to locate a problem other than agreeing that there is a noise.
Our mechanic replaced the front struts and strut mounts, the rear shocks and has gone over the entire suspension and transmission more than once. The noise is very loud, like something is broken but despite three separate shops checking it out nothing can be found.
Any possibility is could be something with the automatic side doors, such as the motor being loose or something strange like that? If it didn't have this clunking sound the ride would be very smooth and quiet. It doesn't affect the ride at all. The other bit of info here is that we haven't owned this van for very long, we bought it as is thinking that it needed shocks or struts. They've been replaced but the sound is still around!
Camry 2012+ :: Loud Thud Going Over Speed Bump - Something Hitting Floor Board Of Car
2012 SE with 4 cylinder 35K miles. When the front wheels go over a speed bump at a couple of miles per hour I get a noise which sounds like something hitting the floor board of the car. It is a loud single thud. Much deeper and louder than a loose seat would make.

Just recently I my truck has developed a thumping sound that I can feel under my driver side floor board. The weird thing is that it does not do it all the time. But yesterday I noticed it for a more extended amount of time.

The sound system in my 2008 LS 460 suddenly stopped and a loud thumping noise comes up in all speakers even if the radio is turned off. There is no music at all only that loud noise. Bluetooth does not work as well as command voice and the GPS guiding system. I had to remove the fuse to stop the thumping sound. To answer my telephone I must pull on the side of the road and turn off the motor. Car dealership said that it is the first time they see that. The car is scheduled to be looked at in a couple of days.

In February 2014 I purchased a 2011 Honda CRV. I often travel and am gone for about a week. Every time I come back the rear brake are rusted. They have a loud thumping and grinding sound. I immediately took the car back to Honda dealership (2 time) both times they 'shaved' the roaters. I then contacted Honda headquarters to report the issue. They told me to deal with the dealership and take it to a local mechanic for other opinions. Car Talk will be my second opinion. Honda dealership told me that this is just the way it is. This is my third Honda, I have NOT had this problem before.
View 8 RepliesCivic - Honda :: Loud Fast Rhythmic Thumping Sound When Got Onto The Highway
I was driving my son to Mygym this morning and everything was completely normal, but when I got onto the highway for the last 5 minutes of the drive my car started making a loud fast rhythmic thumping sound. I thought it was my tire and slowed down to stop... and then in stopped. So I went a little faster and as soon as I hit 50, it started again. I slowed down and drove the rest of the way to my sons class and looked at my tires and they looked fine to me (I have no idea what a tire should look like, but I can tell if one is very flat... I think). I also looked under the car for any obvious debris or whatever and didn't see anything.
We had our class and when I got back on the highway and accelerated to 50, it started back up again, so I slowly drove to our exit. By the time we were nearly home I wasn't even thinking about the problem anymore, but in the 45 zone near our home it started thumping again... sure enough, I was going 50. I am also wondering if it is safe to drive my car as long as I stay under 50? I have no other means of transportation and we need to go out pretty often (daily) for classes and therapies for my son.
Touareg :: Loud / High-pitched Mechanical Sound Coming From Center Of The Dash?
I have been getting a loud, high-pitched mechanical-sounding noise coming from the middle of the dash, near the CD player. It lasts only a few seconds, but it scares the sh!t out of me every time! It happens out of the blue after I've been driving for a few minutes about every 3 weeks or so. The sound is almost impossible to describe...but if you've had it happen you probably know exactly what I'm talking about. It happened today while I was listening to a CD, so I can't imagine it's the player that's doing it. Non-Nav/Air V8

View 6 RepliesPontiac - Montana :: 2001 - Overheating / Low On Coolant
I have a 2001 Pontiac Montana that was overheating. It was low on coolant, and using coolant. I took it to a mechanic who checked it out and found exhaust gases in the coolant. He initially told me that it was a bad head gasket. After doing a bit of research, I am told that it could also be an intake manifold gasket. I know I am losing coolant, but I cannot tell where. I don't think it is going into the oil, as my oil level does not go up. I do not see coolant leaking below the vehicle, so perhaps it is going into the exhaust? Or leaking slowly on top of the engine where it is burned off before it can go on the ground.
Is there any test I can do to determine which gasket is bad before tearing into the vehicle? I thought about sending an oil sample off to determine if I am getting any coolant in the oil, but I don't know if that would be useful information at this point.

I have a 2001 Pontiac Montana van, when i drive i feel like there is just not enough power there. Most of the time when i hit 30mph the engine drops in power, hard to explain so I will try my best. I get in turn the key starts right up with out any hesitation what's so ever! I leave for work, while driving when I come to a stop sign and stop and take off its gets sluggish so while my speedometer is going up my movement is not changing as it should so needless to say I have to do 80 85 mph just to keep up with the average moving can at 70mph.
Once in a while I will give it some gas and let go of it and it would back fire a little not sure why. Recently I had new head gaskets put on cause temperature was not staying where it was suppose to be, they smooth out the headers and did a tune up, not sure about the timing, New fluids, once in awhile the temp would climb but that cause of the fans. Took it to AutoZone they did a obd code check came back with O2 senser and nothing else, so if I replace this will it bring my van back to normal running operation? And would it be anything I could check to rule out?
Pontiac - Montana :: 2006 - Check Gas Cap / Code P0455
I have a 2006 Pontiac Montana SV6 with 80,000 miles on it. Recently the dashboard warning "check gas cap" has started coming on. I have replaced the gas cap and cleared the code and it is doing it again. It seems like it is more likely to do it when the gas tank is 1/2 or less full but it also did it today with almost a full tank. The code from the computer said P0455, what this could be?
